Absolutely. This already works. What doesn't work yet is the
other way round - when they actually do know the brand :-)

All this is useful and planned. Probably not all of it in
0.6 though which will allow all of the above combinations
but not necessarily *help* with all of them as much as would
be possible.

Strength will be a phrasewheel returning matches based on
previous use of that substance but allowing another
strength, too, yes.

Yes, absolutely.

Yep, I am working on that right now :-)

yes

I thought about that but wasn't sure I can get it to work
predictably and sanely.
